Received April 2007 Accepted June 2007 INTRODUCTION Although leiomyosarcoma is among the most common nonepithelial retroperitoneal tumors along with fibrosarcoma, liposarcoma, and malignant lymphoma, it only constitutes 5% to 15% of all retroperitoneal tumors. About 70% of leiomyosarcomas are found in the retroperitoneal space.(1) Extensive surgical resection for achieving complete removal and ...

Idiopathic retroperitoneal fibrosis (IRF) entirely confined to the pelvic cavity is an extremely rare clinical entity. Herein, is described the case of a 36- year old male who presented with clinical and imaging manifestations of a large pelvic tumor. Exploratory laparotomy revealed a large mass in the right pelvis originating from the retroperitoneal space, displacing the right iliac vessels, ...

AIM It presents a clinical case of undifferentiated retroperitoneal liposarcoma with 5 years' recurrence from the first operation for the rarity of the occurrence, the problems related to surgery and complementary therapeutic approach. MATERIAL OF STUDY Male patient aged 73 was operated for removal of retroperitoneal mass with involvement of the right kidney at the Second University of Naples...

The association of idiopathic achalasia with ankylosing spondylitis and retroperitoneal fibrosis, to our knowledge not previously reported, is described in a 54 year old woman. We suggest that the consecutive occurrence of ankylosing spondylitis and retroperitoneal fibrosis, two well-known autoimmune disorders, before the presence of achalasia, reinforces the theory of autoimmunity in etiopatho...

INTRODUCTION Varicocele is a common disease in adult men that can be treated with one of several surgical methods. Each technique has advantages and disadvantages, and conflicting results have been obtained by different studies. To evaluate the most effective surgical techniques used in adult bilateral varicocele, including minimally invasive procedures, we compared the outcomes of three common...

Retroperitoneal sarcomas are rare and treatment should optimally be centralized. Despite successful centralization with 90% of the patients referred prior to surgery, delays occur, which led us to assess lead times in a population-based series. Method. Patients diagnosed with retroperitoneal sarcoma in the southern Sweden health care region 2003-2009 were eligible for the study. Data on referra...

Fetus-n-fetu is a fascinating diagnosis explaining the development of ‘baby within a baby’. It results out of a monozygotic diamniotic twin pregnancy in which a twin is absorbed into the body of its sibling. The surviving twin often presents with abdominal mass and the diagnosis is only confirmed by surgical exploration. It is often mimics retroperitoneal teratoma on imaging and poses a challen...

Complications of dropped gallstones after laparoscopic cholecystectomy are infrequent but retroperitoneal abscess is extremely rare. We present a new case, discuss causes, diagnostic methods, preventive measures and therapeutical options.

Foetus in foetu, a descriptive term attributed to Meckel (circa 1800), should be applied only to those rare cases where a parasitic twin is found included within the abdomen of its partner. Lord (1954; 1956) reported two definite cases and reviewed other possible cases. In contrast, the variety of teratoma which occurs in the retroperitoneal space is much less defined. Since the description of ...
